The element that shows greater ability to form p\(\pi\)-p\(\pi\) multiple bonds, is :
Show Hint
- Si
- Ge
- C
- Sn
The Correct Option is C
Solution and Explanation
Such overlap is effective only when the atoms are small, so that the p orbitals are close to each other.
Atomic size increases down group 14: C < Si < Ge < Sn. The 2p orbitals of carbon overlap very well sidewise (C=C, C\(\equiv\)C, C=O, C=N), while for Si, Ge and Sn the larger, more diffuse p orbitals overlap poorly, so they hardly form p\(\pi\)-p\(\pi\) multiple bonds.
Hence carbon shows the greatest ability.
Answer: (3) C

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
